Stantec signs Letter of Intent to acquire Wenck, a 300-person environmental engineering firm - Seite 2

• Former Advance Machine Facility: The historic manufacturing facility was the source of chlorinated releases to soil, groundwater, and vapor for decades. When the site was redeveloped in the late 1990s into residential homes, Wenck undertook a full remedial investigation of the site, including soil, groundwater, surface-water, and soil gas to assess potential risk. Based on the results, site remediation consisting of groundwater pump and treatment started in 2004. Over the years, upgrades have been made, and Wenck is currently designing a significant expansion of the groundwater pump and treatment system to include two additional deep well systems for advance remediation.
• Canola Oil Processing Facility: Wenck was the lead engineer for a Canola Oil Processing Facility. As lead engineer, Wenck completed the in-house design services, used air dispersion modeling for the air permitting, and managed all subcontractor design services. Wenck’s project services totaled more than 39,000 hours, including leading the mechanical design, electrical design, process/process piping design, site layout, and process controls design.
• Palmer’s Creek Wind Farm: A large wind energy conversion system with a 44.6-megawatt nameplate capacity was proposed near Granite Falls, Minnesota. The project included 18 wind turbines and associated facilities located on approximately 6,150 acres of privately-owned land. Project construction and operation required numerous local, state, and federal regulatory requirements. Wenck assisted Palmer’s Creek by completing necessary pre-construction surveys, biological assessment, Minnesota site permitting, and federal environmental review.
• Fridley Civic Center Stormwater Reuse: The Fridley Civic Center Complex includes a new city hall, police and fire departments, and public works facility. The City of Fridley saw an opportunity to bring their civil services and the surrounding community together by making stormwater a focal point of their complex – a living example to promote best management practices to protect an important regional water resource, Rice Creek. Wenck’s site design included a central water feature with a recirculating three-step aerated pool. The water feature serves as a central amenity connecting the different uses on site and creates a community gathering space. It also serves as a reservoir for stormwater reuse through onsite irrigation of green spaces. The Civic Center Complex was recently named 2020 Project of the Year by the American Public Works Association-Minnesota (APWA MN) Chapter.
• Biochar and Iron-Enhanced Sand Filters: One of the most common impairments to water quality in lakes and streams is bacteria. Wenck partnered with the Shingle Creek and West Mississippi Watershed Management Commissions to obtain a federal grant to fund a project to field-trial three applications of a new technology to treat bacteria in real-world stormwater runoff. Wenck designed three applications of biochar- and iron-enhanced sand filters, and the project tested the effectiveness of these filters. The applications were successful at removing 60 – 95 percent of bacteria, and Wenck continues to work with the Shingle Creek and West Mississippi Watershed Management Commissions to refine designs, better understand longevity and maintenance needs, and identify additional applications and locations for treatment of bacteria in stormwater runoff.
